Over time, internal epoxy insulation breaks down, leading to micro-arcing and internal winding shorts. Concurrently, factory spark plug gaps erode from high combustion chamber pressures, increasing the required firing voltage. This dual degradation triggers common P0300–P0304 misfire trouble codes, hesitation under heavy towing loads, unburnt hydrocarbon buildup, and erratic throttle response.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis full overhaul kit matches OEM primary and secondary winding ratios, using high-dielectric epoxy potting to withstand under-hood heat soak and eliminate secondary voltage leakage. The replacement boots feature high-grade silicone to prevent thermal degradation and valve cover oil intrusion. Paired with fine-wire iridium spark plugs, the kit reduces the required arc voltage, stabilizes flame kernel expansion under high cylinder pressures, and maintains precise gap tolerances significantly longer than standard copper alternatives.
